ARCHERY BOW TORQUE REDUCING DEVICE Filed July 14, 1965 Kati E. Cress United States Patent 3,468,297 ARCHERY BOW TORQUE REDUCING DEVICE Keith E. Cress, 122 Hollywood Ave., Santa Cruz, Calif. 95060 Filed July 14, 1965, Ser. No. 472,407 Int. Cl. F411) /00, /00 US. Cl. 124-24 2 Claims This invention relates to minimizing the dispersion caused by the torque which is generated whenever an archery bow is shot.

It is an object of the present invention to provide a weight and a novel means for securely fastening subject weight to the nonworking portions of an archery bows limbs, thereby absorbing the torque which is generated by the bow limbs when the arrow is released, thereby greatly increasing the accuracy of the archer.

It is another object of the present invention to provide this means of securing the weight to the bow in such a manner that the weight may be moved in or out on its attachment and the attachment may be moved up or down on the bow, thereby providing a unit that is adaptable to any bow.

It is another object that this novel means for attaching this weight to the bow be so done that it may be readily attached or detached from the bow quickly and easily without harm to the bow.

It is a further object of this invention to provide a dispersion minimizing unit which is of simple construction, is inexpensive to manufacture, has a minimum of parts, efiicient to use and may be quickly and easily aflixed to an archery bow.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

FIGURE 1 is a side elevational view of a preferred embodiment of the present invention to include both the weight and the means by which it may be secured to the bow;

FIGURE 2 is an end view from the left end of FIG. 1;

FIGURE 3 is a side view of the same weight which shows it to be bulged out at the center and also that it is concave at the top to permit a match with the semiround face of the attaching unit as clearly seen in FIG- URE 2;

FIGURE 4 is a side elevational view of two units of the invention shown in operative use on a target bow.

Referring now in greater detail to the drawing, 10 represents a molded plastic body having three externally notched edges 13 running the length from the middle to one end so as to function as threads, and flaring outward without notches from the middle to the other end to join the base 21.

The base is provided with four pins 14 which is the means by which the entire unit is secured to the bow 17 by use of two heavy duty rubber bands 20.

'ice

Two internally threaded sleeves 12, are screwed on to the externally threaded portion 13 so as to receive the concave, elongated portion 16 of the main weight body 11.

A strip of corduroy rubber 15 is secured to the face of the base 21 to prevent the unit from slipping or marring the bow.

To mount the device, the rubber bands 20 are slipped over the pins 14 and then stretched and wrapped around the bow at number of turns so that it will be obvious to the user that the unit is securely afiixed to the bow, then the loose end of the rubber band is slipped over the other pm.

The lead weight 11 is then positioned on the threaded portion 13 of the unit 10 and the two sleeves 12 are then advanced toward each other until the sleeves wedge the elongated portion 16 into engagement with the threaded shaft, thereby holding the weight -11 securely in place.

It will be obvious to anyone skilled in the art that two of these complete units are necessary on a single archery bow, one above the handle and one below as seen in FIGURE 4, for most applications, however, some individuals will use a single unit mounted below the handle so that its added Weight will serve to align the bow vertical- 1y.

While various changes may be made in the detailed construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What I claim as new and desire to protect by Letters Patent of the United States is:

1. An oscillation dampening unit comprising a rectangular base, an elongated threaded shaft fixedly mounted upon one face of said base, four pins upstanding from said one face, one pin positioned adjacent each corner of said base, a resilent pad secured to the other face of said base, two internally threaded sleeves threaded onto said shaft, and a weight having a base means adapted to be positioned between said two sleeves and to be wedged against said shaft by movement of the sleeves toward each other.

2. The device of claim 1 wherein said base means is elongated and concave on the side which is adjacent said shaft.
